Continuously gummed tape is used very largely in the place of string, for securing food products and other articles which are com pletely enclosed in paper wrappers, and no objection applies to such use because no harm results even if the tape adheres at any portion of its length to such paper wrappers. But to employ continuously gummed tape for enclosing folded shirts or other articles,when

nothing is interposed between the tape andthe otherwise bare article, would be objectionable for obvious reasons. Such continuously gummed tape is commonly and conveniently supplied from a cbil by devices havand usually moistening end portions.

' vide the bands can be no longer than the One of he ob'ets of our invention is-to provide paper band material which is of indeterminate length, and preferably coiled or folded, with thickened and gummed portions at predetermined intervals, whereby definite lengths of bands may be separated and served from thegreater length of material, by the employment of mechanism somewhat similar to the dispensers now used for the ordinary continuously gummed tape, each l.definite length carryin a limitedamount of gum at or near one 0 its ends, or sometimes at or near both ends'as hereinafter explained.

So far as we are'aware, themost economical prior method of maln'ng paper bands having I gum only at the ends, necessltates the cutting of aweb of paper transversel with the -re-. sult that the strips cutfrom t e web to pr0.-'

width of the web. I As. is well known, the web can be no wider than the limited'capacity of the paper-maln'ng machine. Consequently such stri s orbands can .be but a few feet long. owever, in such bands-the, grain of the paper is cro$wise because the-manufacthe .web results in the grain being lengthwise of the web. Obviously, therefore,

' 5 since paper is always strongerin the, direc- -1n paper and glue substances used.

tion of its grain than transverse of the web,

bands which are cut transversely from the web have a crosswise grain and are liable to be torn crosswise. Therefore another object of our 1nvent1on 1s to provide paper bandsor equivalent articles supplied by a strip of any arate them singly from a lot. In handling they become scattered over the bench or table which not only causes spoilage but requires time to, pick up for use such as when banding.

bread, cake, or the like, in large quantities. further ob ection to the use of separate individual bands is that they have to be selected from a pile or stock? by hand, and the gum molstened b a sponge. This not only consumes time, ut the operators fingers become sticky and dirty which is obviously obj ectionable, especially when handling'food. Such bands can not be practically supplied by dispensing machines because of the variavt ilons en such bands are stacked in a pile, the ends of.

the bands having the adhesive are the thickest, and consequently only a few of such bands can be in a pile without tippin over from properpiled condition.- There ore another object of our invention is-to provide adhesive-carrying band material in such form that individual bands can be taken therefrom and used without disarranging the. rest of the supply. 1

'Another object object, of our invention is provide paper band material, with adhes ve-at intervals, the whole being of such ortions, thereof, at pre-.

construction that determined interva ,canbe employedyto operate or control necessary portions of a dispenser to facilitate the successive separation of the lengths desired for use. -With the above-mentioned objects in view, and others hereinafter explained, the invention consists in; the articles and the method of making them substantially ashereinafter describedand claimed a v Of the accompanying drawings Figure 1 is a side elevation of a coil of the band'material, which coil may be much larger than illustrated. i Figure 2. is a face view of an indeterminate length ofoneform of the band material, partially broken away to indicate that the sections of the strip may be of-any length.

Similar reference characters indicate similar parts'or features in all of the views.

Referring first to Figures 1 and 2, a strip of paper a, of the width that may be desired, and cut from a web of paper in the direction of the length of the web so that the grain of 25 the strip will be lengthwise thereof. At intervals spaced according to the length desired for the bands, the strip is transversely perforated as at a, and adjacent to each line of perforations there is adhesively afiixed 3o thereto a piece of suitable material such as kraft paper as illustrated at b. For the sake of brevity of terminology, the members I) will be hereinafter referred to as tabs. In most of the forms hereinafter described, the tabs 6 are double-coated withv adhesive material; that is, both surfaces are gummed so that their inner surfaces can be secured adhesively to the stripmaterial a whiletheir outer or upper surfaces'will present adhesive by means of which a band section, when separated from the long strip, can be employed intheusual manner to enclose or Wrap the article for which it is intended. As-illustrated by Figure 2, the tabs b are circular in form, and as illustrated by Figure 4, they are rectangular. In both cases the tabs are of less width than the width of the band, the advantage of which will now be explained.

When the end of a band has adhesive ex 5 tending its entire width, there is always a liability of one side margin of the gummed.

portion or member becoming stuck to the shirt or other article to which the band is applied by overlapping the gummed portion (moistened as customary) upon the other end portion of the band when the band is wrapped around the article. It is not easy to so aline the overlapped portions as .to prevent this.-

But since the tabs 1) are of less lateral area than the bands, leaving entirely ungummed areas of the band each side of the tabs, there is less likelihood of any adhesive'contacting with the enclosed article'when the bands are applied in the usual manner.

The presenceof the tabs 6 at spaced into any desired lengthwise portion ofthe band.

tervals along the strip a results in the article as a whole being increased in thickness at those points adjacent to the perforations a, and in makin the long strip stronger at those points than e sewhere, and reducin liability 0 of the strip being torn 9. art elsew ere than intended to supply a sectlon of the predetermined length. In other words, the improved strip has the characteristic that if a user should try to tear the strip a by hand, the tabs 6 will not only indicate the proper place in the length of the strip to. effect severance, but aid in controlling or confining the location of the severance to that point or place. Said increased thickness due to the tabs 6 may o also be utilized to control or operate a dispenser mechanism having a severing blade. Owing to this last feature, it is not always necessary to transversely perforate the strip a, since the blade of such dispenser will effect 5 separation of the band sections successively.

As indicated in Figure 3, the tab 6 ma extend over the line of perforations a, wit a free part 12 forming a flap that is not adhesively secured to the-strip a. .The under no surface of the flap 12' carries gum, but the entire upper surface of the tab and its flap will be left ungummed. Then, when a section is parted on the line a, it will have a gummed tab extending from its end.

As illustrated by Figure ,5, the line-of perforations. a is formed in the tab as well as in the strip a. When so made, the tab 6 is adhesively secured to the band throughoutv its area, and also presents an entire drygummed outer surface. When the long strip is made this way, each band section will have an adhesive carrier a ach of its ends. Such type of packaging band is desirable ,for someuses, such as when it is desired to prevent the band from slipping oif from the wrapped or enclosed article. To effect this, one end of the band can be stuck'to the article wrapped, I and the other end overlapped upon and stuck In the structure illustrated by Figure 6, no transverse perforations are employed. Sometimes theincreased thickness of the strip at intervals, due to the presence of the tabs, enables a band section to be separated by a tearing action guided by the edge of the tab. Said Figure 6 also illustrates the tab b as provided with a partially cut out middle portion providing a flap b'.' Iii this form, the upper or outer surface of the tab andits flap carry no adhesive. The under surface of the tab and its flap is gummed, but only the marginal areas of the tab are secured to .the strip a. The flap' b is left free, but with its under gummed surface dry so that, when moistened, it can be utilized extensions 6" which may be utilized to control or operate a dispenser mechanism, and which also provide marginal portions on which identification or other marking may be exhibited. 4

Having now described our invention, we claim 1. A strip of paper of indeterminate length having tabs adhesively secured thereto at predetermined intervals, the exposed surfaces of said tabs being gum-coated. 2. A strip of paper of indeterlninat length, the grain of the paper extending lengthwise thereof, said strip having tabs adhcsively secured thereto at predetermined intervals, the exposed surfaces of said tabs being gum-coated.

3. A strip of paper of indeterminate length having tabs adhesively secured thereto at predetermined intervals, the exposed surfaces of said tabs being gum-coated and said strip being weakened adjacent to said tabs.

4. A strip of paper of indeterminate length having tabs adhesively secured thereto 2 at predetermined intervals, said tabs being of less width than the strip and the exposed surfaces of said tabs being gum-coated.

5. The method of making packaging-band material, consisting in cutting a strip length wise froma web of paper to cause the grain of the paper to run lengthwise of the strip, and adhesively aflixing to the strip, at predetermined intervals thereof, tabs having exposed gum-co'ated surfaces. 6. The method of making packaging-band I material, consisting in cutting a strip lengthwise from a web of paper to cause the grain of the paper to run lengthwise of the strip,

adhesively aflixing to the strip, at predetera 46 mined intervals thereof, tabs having exposed gum-coated surfaces, and transversely weakening the strip adjacent to said gum-carriers.

In testimony whereof we have aifixed our signatures. a LEON E. LA BOMBARD.
